Usage

"print"(x, digits = getOption("digits"), prefix = "\t", ...) "print"(x, digits = getOption("digits"), ...)

Arguments

x

object of class "mpe.test" or "power.mpe.test".

digits

number of significant digits to be used.

prefix

string, passed to strwrap for displaying the method component of the mpe.test object.

  print(pkv, digits =  4) # using less digits than default
